Why does my 10 wk old DD2 fuss in the evenings when I try and latch her on the left breast?

[HeinzSight]

It's like she doesn't like being held in the cradle hold on the left, but if I try the rugby hold she'll feed on the left. It doesn't bother her during the day.

Also, how long on average do babies stay on the breast at this age for each feed?

Hello
My DD loved my left boob and hated my right one. Now she is 5 and half months and she loves BOTH.
My DD stayed on for a minimum of 20 mins every time and she was 9lb 7oz @ birth.
I do not think that there's a corelation with day and night here.
Best wishes...xoxo

It turned out she has an ear infection

Am SO upset as DD1 (2) has been riddled with them.

Oh dear. Chin up
